Sage of Hours + The Ten Rings + Psychic Frog + Lyla, Holographic Assistant

Sage of Hours

The Ten Rings

Psychic Frog

Lyla, Holographic Assistant

How it works

1. If you have six or more cards in hand, activate Psychic Frog by discarding a card.
2. Repeat step 1 until you have five or fewer cards in hand.
3. At the beginning of your end step, The Ten Rings triggers, causing you to draw cards until you have ten cards in your hand.
4. Lyla triggers for each card drawn, putting that many +1/+1 counters on Sage of Hours.
5. Activate Sage of Hours by removing all +1/+1 counters from it, causing you to take at least one extra turn after this one.
6. Repeat each turn.

This clever loop harnesses the card-draw engine of The Ten Rings to continuously feed your resources, refilling your hand at the end step whenever it falls below ten cards. As you discard down via Psychic Frog's ability to adjust your hand size, Lyla, Holographic Assistant leverages each of those card draws to shower your board with counters. Those accumulated resources culminate in Sage of Hours, whose ability cashes in those exact counters to perpetually chain extra turns, locking down the game in formats like commander, oathbreaker, and vintage.
